Additional information
Conclusion on classification
The substance meets classification criteria under Regulation (EC) No 1272/2008 as hazardous to the aquatic environment: Chronic Category 3 : H412
The test item is ‘readily biodegradable’ (10-day window does not apply, OECD 2006).
The test item has a measured log Kow > 4.0 although information on structural analogues indicates a Bioconcentration Factor (BCF) is considered < 500 L/wt
The test item does not indicate EC50/LC50 < 1 mg/L
However, there is a relevant EC10 (algae) or NOEC (algae) < 1 mg/L in available studies.
Daphnia EC50-48h = 1.3 mg/L (95% CL: 0.90 – 2.0 mg/L) based on TWA concentrations, 48-hour, freshwater, OECD 202, 2014
EC50-72h (Read-Across: undec-10-enal ; aquatic algae; growth rate) = 1.1 mg/L (C.I. 0.63 -1.3 mg/L), 72 hour, freshwater, OECD 201, 2013
NOEC (Read-across: undec-10-enal ; aquatic algae; growth rate) = 0.34 mg/L, 72 hour, freshwater, OECD 201, 2013
QSAR: Fish LC50-96h = 1.3 mg/L, iSafeRat® HA-QSAR toolbox v2.4, KREATIS SAS, 2018
Toxicity to microbes:
ASRIT: EC50-3h = 200 mg/L (nominal), 20 °C, OECD TG 209, 2018
ASRIT: EC20-3h = 130 mg/L (nominal), 20°C, OECD TG 209, 2018
ASRIT: EC10-3h = 100 mg/L (nominal), 20°C, OECD TG 209, 2018
ASRIT: NOEC = 125 mg/L (nominal), 20 °C, OECD TG 209, 2018
